Zeiss Personalised PRK / TransPRK (ASA)

PRK stands for photorefractive keratectomy.  In PRK treatment, laser light is used to change the refraction and focusing of the cornea with world’s most advanced Zeiss MEL90. We gently remove the skin from the surface of the cornea and reshape the cornea from its top.  The skin grow back naturally and the process can take 3 days.

PRK/TransPRK (ASA) Explained Further…

In PRK laser eye treatment, the surface layer (epithelium) of the eye is treated with alcohol and Mitomycin-C solution. The permanent corneal layer beneath the epithelium is then reshaped, correctly readjusting the vision. The surface layer heals naturally by the eye in 72 hours.

In Zeiss Personalised TransPRK (ASA All Laser Surface Ablation) laser eye treatment, similar to PRK, the surface layer of the eye is treated with LASER ONLY.  The cornea below the epithelium is then reshaped, correctly readjusting the vision. The surface layer heal naturally in 72 hours.

In PRK/TransPRK ASA eye treatment, no corneal flap is made. The recovery time is much slower in Zeiss Personalised PRK than Zeiss Personalised TransPRK (ASA). PRK takes longer to achieve results than TransPRK ASA. The results of PRK/TransPRK and Bladeless LASIK are exactly the same.

Zeiss Personalised Double Laser ASA TransPRK

It is now possible to perform “no touch” laser eye surgery with the Zeiss advanced MEL90 laser. Transepithelial Photorefractive Keratectomy, or TransPRK (ASA), is the surface treatment where the eye doesn’t require contact with any surgical instrument. Due to smaller laser surface area, patients who have TransPRK (ASA) benefit from a quicker recovery time and ultimately achieve outstanding results.

Procedure

TransPRK ASA is a new one-step, incision-free procedure. Using the MEL90 laser, the skin of the eye cornea is gently removed and the cornea shape is precisely changed.  The procedure takes less than one minute. Unlike LASIK, there is no incision or flap created in the cornea with TransPRK (ASA).

Benefits of Zeiss TransPRK ASA

  • No touch – all laser
  • It removes the epithelium more precisely and easily than in PRK
  • Smaller corneal surface laser treated area so it heals quicker
  • The epithelium and stroma can be treated at the same time and with greater accuracy
  • Overall treatment time is shortened than PRK
  • It minimizes the risks of corneal dehydration than PRK
